FINALLY got to West Virginia with the new RZR! It performed great on the mountains, even with my 300 lb. cousin in the passenger seat instead of my petite wife. Took it up some long, tall trails, and it didn't hesitate. The weather gods weren't real favorable, so we only put 82 miles on it, but I am very satisfied with the performance. The sales person was right, for a change, and the 570 did all I needed it to. An 800 would have been overkill. I am seriously thinking of taking it to eastern Kentucky next month, since I have never ridden there. Also, there is a chance to possibly see elk there. Anybody have any suggestions on the best place for that in Kentucky? See you on the trails.
